The Mississippi River is the second-longest river in the United States and fourth-longest in the world. The river is about 2,320 miles (3,734 km) long and its drainage basin covers an area of 1,151,000 square miles (2,981,076 sq km). The source of the Mississippi River is believed to be Lake Itasca in Minnesota and its mouth the ​Gulf of Mexico.

There are a number of tributaries large and small that flow into the river, including the Ohio, Missouri, and Red rivers. The river doesn't just border states, it creates borders (or partial borders) for several states. The Mississippi River drains about 41% of United States water.

These are the 10 states that you would pass through if you were to travel from north to south down the river. The area, population, and capital city of each state have been included for reference. The population estimates were reported by the United States Census Bureau in 2018.

The headwaters of the Mississippi River have historically been recorded as being in Lake Itasca, in the northern part of the state of Minnesota. There is some disagreement amongst geologists about whether this is really the river's beginning—some say that the headwaters might be in North Dakota—but Minnesota is generally accepted as the northernmost state that touches the river.

A portion of Kentucky bordered by the Mississippi River, known as the "Kentucky Bend", is accessible by land only through Tennessee. It is a small peninsula that technically belongs to Kentucky but is not in physical contact with the state at all.

When surveyors were first delineating the boundaries between the states of Kentucky, Missouri, and Tennessee, their estimates of where the ​Mississippi River would meet their line was off. The river snaked where it was expected to be a more direct path through the states and this was only discovered by surveyors after their borders were already finalized—they gave the unconnected hunk of land to Kentucky.
